    MasterSet R 100

    Set retarding admixture

    Formerly: Pozzolith 100 XR

    How does MasterSet R 100 work?

    MasterSet R 100 ready-to-use liquid admixture is used for producing more uniform and predictable quality concrete. Placing and finishing requirements are facilitated because this admixture retards setting time.

    Recommended uses:

    • Prestressed concrete
    • Precast concrete
    • Reinforced concrete
    • Shotcrete
    • Lightweight concrete
    • Pumped concrete
    • 4x4 Concrete
    • Pervious concrete
    • Self-consolidating concrete

    What are the unique features of MasterSet R 100?

    • Reduced water content required for a given workability
    • Retarded setting characteristics
    • Controlled retardation – depending on the addition rate
    • Full-form deflection can take place (before concrete sets) in extended pours for bridge decks, cantilevers, non-shored structural elements, etc.
    • Meets ASTM C 494/C 494M requirements for Type B, retarding, and Type D, water-reducing and retarding, admixtures

    What are the benefits of MasterSet R 100?

    • Improved workability
    • Reduced segregation
    • Superior finishing characteristics for flatwork and cast surfaces
    • Flexibility in scheduling of placing and finishing operations
    • Offsets effects of early concrete stiffening during extended delays between mixing and placing
    • Helps eliminate cold joints
    • Peak temperature and/or rate of temperature rise in mass concrete lowered thereby reducing thermal cracking
    • Increased compressive and flexural strengths
